Soft Start/Smart Start

™

System (RTX2000pi and

RTX2500pi only)

“Smart” vs. “Soft”

•

“Smart” refers to the function where the

motor starts and stops when the trigger is

pulled and released. This keeps the

sprayer at full operating pressure and

allows the sprayer to spray immediately

when the gun is triggered.

• “Soft” refers to the function where the

sprayer slowly starts the pump. This

prevents a large “splotch” of material

from being discharged from the gun

when trigger is pulled after the sprayer

has sat idle for a period of time.

Smart Start

The Smart Start System is controlled by

compressed air in the tanks and lines. When

gun is triggered, air flows through the lines

and opens a flow switch. There is also

another pressure switch that senses when

the compressed air system is at operating

pressure. This second pressure switch

allows the sprayer to start immediately when

the sprayer is turned ON charging the

compressed air system to full pressure. This

method keeps the compressed air system at

operating pressure if there is a small air leak

in the system.

Soft Start

The Soft Start System is controlled by motor

power and an air cylinder. When pressurized,

the air cylinder pushes the rollers into the

peristaltic pump pushing material through the

pump. When the motor shuts off, a solenoid

valve relieves the pressure in the air cylinder

causing the rollers to disengage from the

peristaltic pump. When the motor starts again

there is a time delay while the air cylinders

charge and move the rollers into the pump

this is the “Soft Start”.

Setup

3A3258J 11

Setup

1. Connect air hose and material hose to

sprayer air and material hose outlets.

2. Open air valve.

3. Connect air hose to gun.

4. Connect material hose to gun.

5. Make sure burp guard is installed.

6. Install spray nozzle or wide spray disc.

NOTICE

•

Do not store sprayer under pressure.

• Do not allow material to dry inside

pump, hoses, gun or spray system.

• When operating a RTX1400SI and you

are going to stop spraying for more than

five minutes turn sprayer OFF to

prevent shortened pump life.

ti27342a

ti27341a

ti27343a

Before adding material to the hopper,

install the burp guard. When only a small

amount of material remains in the hopper,

the burp guard prevents material from

shooting out when the unit is turned off.

This material could splash in the operator’s

eyes or on skin, or into the air.

ti27344a

Mixing Material

3A3258J 13

Mixing Material

NOTE: Correct material mixture is essential.

The pump will not operate if the mixture is too

thick.

• Mix the material in a separate container

before pouring it into hopper.

• Use Material Thickness Gauge to

determine if mixture is thin enough to

spray.

• The Material Thickness Gauge will only

determine if the material is thin enough

to pass through the pump. For some

applications or for higher speed

spraying, your mixture may need to be

thinner.

• For best results, do not use partial bags

of material.

1. Mix the material and water in a

separate container.

Dry Mix - 40 lb (18 kg) bag

Carefully mix texture material and water

according to manufacturer instructions

on bag.

Premix

Slowly add approximately 2 to 4 quarts

(1.9 to 3.8 liters) of water to a 5 gallon

(18.9 liter) bucket of premix.

2. Agitate to mix, using a half-inch, variable

speed drill with mixing paddle, to a

smooth, lump-free consistency.

3. Allow ceiling texture to set for at least 15

minutes. Then remix prior to use.

4. After texture material is thoroughly

mixed, gently set ball end of Material

Thickness Gauge on surface of mixture.

NOTE: For an accurate test, be sure gauge is

completely dry and clean every time it is

used.

5. Observe the ball on the material. When

the material is thin enough to spray the

ball will sink completely into the mixture

within 10 seconds.

6. If the ball does not sink completely into

the mixture within 10 seconds, add more

water, agitate and try test again.

7. Once material is mixed pour material into

the sprayer hopper. See Operation,

RTX1400si 230V, RTX2000pi and RTX2500pi

Adjusting the System

Sufficient fluid output (volume and pressure)

and good atomization are a balance of

atomizing air, material thickness/material

flow and nozzle selection. Achieving the

correct balance for your application requires

experimentation to achieve desired results.

Keep in mind these important points when

adjusting gun:

• Select proper nozzle for your

application. See Nozzle Selection

Chart. Remember, the larger the

nozzle, the heavier the pattern.

• Start sprayer with gun air flow valve

completely open. Trigger sprayer gun. If

needed, slowly close gun air flow until

you get a good spray pattern. Use mini-

mum amount of air at spray gun to

achieve proper spray pattern and to

minimize bounce back.

+ Test spray pattern on cardboard. Hold

gun 18 to 24 in. (45.7 to 61 cm) from

surface. Use this spraying distance for

most applications.

• Air and material flow adjustments are

made at the gun on all units.

+ Opening air valve increases air flow

through gun, which decreases texture

material flow through pump.

+ Closing air valve decreases air flow

through gun, which increases texture

material flow through pump.

To achieve uniform spray pattern, adjust air

valve and flow adjustment nut on gun. If you

do not achieve the desired pattern, change

nozzles, see Recommended Nozzle

Selection Charts, page 15.

To Get Less Material

Try one or a combination of these methods:

• Open air valve.

• Turn gun flow adjustment nut

counter-clockwise to decrease flow.

• Use smaller nozzle.

To Get More Material

Try any one or a combination of these

methods:

• Close air valve.

• Turn gun flow adjustment nut clockwise

to increase flow.

• Use thinner material mixture.

• Use a larger nozzle.

For Continuous Spraying

Use trigger lock to hold trigger open and

reduce fatigue.

Check Material Consistency

Periodically

Check and thin material as needed to

maintain proper consistency. The material

may thicken as it sits and slow down

production. Agitate periodically.

Preventing Material Surge at Gun

Trigger (RTX1400si only)

Pressure will build up in the system when you

stop triggering the gun. To prevent material

surge at initial gun triggering:

• Point gun away from surface you are

spraying when you first pull trigger.

• When you first start to spray, hold the

gun away from the surface and gradually

work your way closer to it.

• Keep gun moving.

• After you begin spraying, trigger the gun

as little as possible.

Soft Start/Smart Start Operation

RTX2000pi and RTX2500pi

Smart Start

Sprayer will start under the following

conditions:

• A new sprayer is plugged in and ON/OFF

switch is turned ON.

• Gun is triggered and air valve is open far

enough.

• There is a small leak in the system and

the pressure drops below the pressure

switch setting. This may appear to be

random operation.

• When a bleeder gun is used.

• When there is no gun or hose connected

to the sprayer.

• When the pressure is relieved by

triggering the gun while the sprayer is

OFF and then turned back ON.

• Prime valve is opened.

• There is a hose failure (leak) in the twin

line hose.

System is functional is to spray material.

• The system is operating properly when a

small amount of material initially comes

out of the gun when triggered and the

volume of material slowly increases to

full spray.

NOTE: Motor runs when gun is triggered.

Sprayer is designed to stop pumping when

gun trigger is released.

Shutdown and Cleanup

Shutdown and Cleanup

NOTE: Keep pump and hose clean when

switching between simulated acoustic,

knockdown and orange peel applications. A

dirty pump can release particles of texture

into the finish.

• To increase pump life, life turn power

OFF when not spraying.

• Before removing material hose, perform

Pressure Relief Procedure, page 9.

Make certain there is no material in the

hose.

• To keep sprayer in good operating

condition, always clean it throughly and

prepare it properly for storage.

When you have finished spraying:

1. Open gun air valve.

2. Turn ON/OFF switch to ON position.

3. Close gun air valve.

4. Trigger gun into bucket until most of

Maintenance

20 3A3258J

Maintenance

Routine maintenance is important to ensure proper operation of your sprayer. Maintenance

includes performing routine actions which keep your sprayer in operation and prevent trouble

in the future.

Texture Hoses

Check hose for damage every time you

spray. Do not attempt to repair hose if hose

jacket or fittings are damaged. Do not use

hoses shorter than 25 ft (7.6 m).

Tips

• Always clean tips with a soft brush after

spraying.

• Tips may require replacement

depending on abrasiveness of texture.

Activity Interval

Inspect motor shield vents for blockage.

Daily or each time you spray

Check sprayer stall (RTX2000pi and RTX2500pi only).

With sprayer gun NOT triggered, sprayer motor should stall

and not restart until gun is triggered again.

If sprayer starts again with gun NOT triggered, inspect pump

for internal/external leaks and check prime valve for leaks.

Every 1000 gallons (3785

liters)

Protect the internal drive parts of this sprayer from water. Openings in shields allow cooling of

mechanical parts and electronics inside. If water gets into these openings, the sprayer could mal-

function or be permanently damaged.
